Gamma Multi-Environment Setup

Overview

Configure Gamma API access across development, staging, and production environments. Since Gamma is a SaaS API with no self-hosted option, environment separation is achieved through separate workspaces (API keys), mock servers for development, and environment-aware client configuration.

Prerequisites

• Separate Gamma workspaces (or at minimum separate API keys) per environment
• Secret management solution
• Completed gamma-install-auth setup

Instructions

Step 1: Environment Configuration

// src/config/gamma.ts
interface GammaEnvConfig {
  apiKey: string;
  baseUrl: string;
  useMock: boolean;
  timeoutMs: number;
  maxRetries: number;
}

function getGammaConfig(): GammaEnvConfig {
  const env = process.env.NODE_ENV ?? "development";

  const configs: Record<string, Partial<GammaEnvConfig>> = {
    development: {
      baseUrl: process.env.GAMMA_MOCK === "true"
        ? "http://localhost:9876/v1.0"
        : "https://public-api.gamma.app/v1.0",
      useMock: process.env.GAMMA_MOCK === "true",
      timeoutMs: 60000,
      maxRetries: 1,
    },
    staging: {
      baseUrl: "https://public-api.gamma.app/v1.0",
      useMock: false,
      timeoutMs: 30000,
      maxRetries: 3,
    },
    production: {
      baseUrl: "https://public-api.gamma.app/v1.0",
      useMock: false,
      timeoutMs: 30000,
      maxRetries: 5,
    },
  };

  const apiKey = process.env.GAMMA_API_KEY;
  if (!apiKey && !configs[env]?.useMock) {
    throw new Error(`GAMMA_API_KEY required for ${env} environment`);
  }

  return {
    apiKey: apiKey ?? "mock-key",
    ...configs[env],
  } as GammaEnvConfig;
}

export const gammaConfig = getGammaConfig();

Step 2: Environment-Aware Client Factory

// src/gamma/factory.ts
import { createGammaClient } from "./client";
import { gammaConfig } from "../config/gamma";

let client: ReturnType<typeof createGammaClient> | null = null;

export function getGammaClient() {
  if (!client) {
    client = createGammaClient({
      apiKey: gammaConfig.apiKey,
      baseUrl: gammaConfig.baseUrl,
      timeoutMs: gammaConfig.timeoutMs,
    });
  }
  return client;
}

// Reset for testing
export function resetGammaClient() {
  client = null;
}

Step 3: Environment Files

# .env.development
GAMMA_API_KEY=gma_dev_xxxxxxxxxxxx
GAMMA_MOCK=false
NODE_ENV=development
LOG_LEVEL=debug

# .env.test
GAMMA_MOCK=true
NODE_ENV=test
LOG_LEVEL=warn

# .env.staging
GAMMA_API_KEY=gma_stg_xxxxxxxxxxxx
NODE_ENV=staging
LOG_LEVEL=info

# .env.production (use secret manager instead)
# GAMMA_API_KEY loaded from AWS Secrets Manager / Vault
NODE_ENV=production
LOG_LEVEL=warn

Step 4: Production Secret Management

// src/config/secrets.ts
// For production, fetch API key from secret manager at startup

import { SecretsManager } from "@aws-sdk/client-secrets-manager";

let cachedKey: string | null = null;
let cacheExpiry = 0;

async function getProductionApiKey(): Promise<string> {
  if (cachedKey && Date.now() < cacheExpiry) return cachedKey;

  const sm = new SecretsManager({ region: "us-east-1" });
  const secret = await sm.getSecretValue({ SecretId: "gamma/api-key" });
  cachedKey = JSON.parse(secret.SecretString!).apiKey;
  cacheExpiry = Date.now() + 300000; // Cache for 5 minutes

  return cachedKey!;
}

Step 5: Environment Guards

// src/guards.ts
function blockProduction(operation: string) {
  if (process.env.NODE_ENV === "production") {
    throw new Error(`${operation} is blocked in production`);
  }
}

// Block destructive operations in production
async function deleteAllGenerations() {
  blockProduction("deleteAllGenerations");
  // ... cleanup logic for dev/staging
}

// Warn about credit-consuming operations in non-production
function warnCredits(env: string) {
  if (env !== "production" && !gammaConfig.useMock) {
    console.warn("WARNING: Using live Gamma API — credits will be consumed");
  }
}

Step 6: CI/CD Environment Configuration

# .github/workflows/gamma.yml
jobs:
  test:
    runs-on: ubuntu-latest
    env:
      GAMMA_MOCK: 'true'
      NODE_ENV: test
    steps:
      - uses: actions/checkout@v4
      - run: npm ci && npm test
      # Uses mock server — no API key needed, no credits consumed

  staging:
    runs-on: ubuntu-latest
    if: github.ref == 'refs/heads/develop'
    env:
      GAMMA_API_KEY: ${{ secrets.GAMMA_STAGING_API_KEY }}
      NODE_ENV: staging
    steps:
      - uses: actions/checkout@v4
      - run: npm ci && npm run test:integration

  production:
    runs-on: ubuntu-latest
    if: github.ref == 'refs/heads/main'
    env:
      GAMMA_API_KEY: ${{ secrets.GAMMA_PRODUCTION_API_KEY }}
      NODE_ENV: production
    steps:
      - uses: actions/checkout@v4
      - run: npm ci && npm run deploy
